比较Python输入列表中的字符串

铁托·尤达

我有这样的代码：

n = list(input().split()) #Input score in alphabet
for i in n :
    if i == "E" : 
        print("You Have Bad Score") #if you have an E score, then you cant pass
    elif len(n) < 7 :
        print("Your score does not qualify") #must enter at least 8 values
    else :
        print("You pass")

# Output
A B C C D D D E = Your have bad score
A B B A A B B C = You Pass
A B B B A = Your score doesn't qualify

但是我的代码中的问题是，当我输入ABCCDDDE时，输出为“ You Pass”而不是“ You score bad”。你能帮助我吗？

您的代码有一些错误的类型或错误：1.x应该为n。其次，尝试使用更具描述性的变量名来帮助您。[注意-您仍然必须修复/解决多个打印语句问题...]

试试这个应该可以帮助您找到答案。

scores = list(input().split()) #Input score in alphabet
print(scores)    # you can comment this out 

for s in scores:

    if any(s == 'E' for s in scores): 
        print("You Have Bad Score")   # earlier bail-out when `E` scores.
        break
    elif len(scores) < 7 :
        print("Your score does not qualify") #must enter at least 8 values
    else :
        print("You pass")

# Output
# A B C C D D D E = Your have bad score
# A B B A A B B C = You Pass

#A B B B A = Your score doesn't qualify

# Sample Run - with # first list of given scores:
A B C C D D D E
['A', 'B', 'C', 'C', 'D', 'D', 'D', 'E']

You Have Bad Score           # changed as the new Req. asked!
